The expansion of rail and highway transport network is an ongoing process. Thus increasing distances have to be managed successfully. Final gear drives are exposed to high stress daily. EMGARD® RW-A is an API GL-5 synthetic gear lubricant designed for extended drain service and improved wear protection in comparison to typical petroleum 80W-90 gear lubricants. The high film strength and the superior low temperature performance of EMGARD® RW-A both result in longer gear life. The anti-rust and anti-corrosion properties of this extreme pressure lubricant further promote extended gear and bearing life.
EMGARD® RW-A is formulated using a synthetic base-stock which has a high viscosity index and an exceptionally low pour point. This lubricant contains extreme pressure additives, as well as rust, oxidation and corrosion inhibitors to protect gears and bearings operated under a wide variety of load conditions. The high and low temperature performance of this product exceeds those of conventional SAE 80W-90, SAE 85W-90 gear lubricants.
EMGARD® RW-A is characterized by the following properties:
A performance comparison on video shows the low-temperature behavior of EMGARD® RW-A to a mineral oil group II oil in a real axle body at -40°C.
Due to the high viscosity of this group II mineral oil at a temperature of -40 degrees the high thread formation is obvious from the very beginning.
EMGARD® RW-A shows even at -40 degrees a low viscosity and thus a smaller thread formation due to its excellent low temperature properties.
The improved low temperature behavior of EMGARD® RW-A assures an increase of lifetime of mechanical components like gears and bearings.
